A light flickers in the silent room. Side by side in twin beds, the girls could be sleeping, except their pale skin is ice cold, and their closed eyes will never open again...

When the bodies of two teenage girls are discovered in a rundown New York City hotel room, Detective Maria Miller is called to the crime scene. The best friends were supposed to be at a sleepover miles away in the suburbs. With no record of the girls checking in and the room on the thirteenth floor closed off to guests, what were they doing there?

Sinister messages on their phones suggest the girls were lured to the hotel, using its reputation for hauntings as bait. The killer left no DNA behind and Maria's efforts to trace their identity leads to a dead end. But Maria feels certain the murderer works at the hotel. How else did they access the room and know it was empty?

While Maria races to interview staff before another body turns up, the hotel manager shares an old newspaper article about an identical double murder decades before. Could the cases be linked? After a key suspect is found dead in his home, a discovery in the hotel room sends shivers down Maria's spine. Can she uncover the secrets of the room on the thirteenth floor before she becomes its next victim?

Perfect for fans of Karin Slaughter, Mary Stone and A. J. Rivers, The Girls on Floor 13 will have you racing through the pages and sleeping with the lights on.
